New regime slabs for FY 2026-27

Budget 2026 kept the slabs introduced the year before. The new regime is the default:

  • Rebate: no tax if taxable income is up to ₹12 lakh (rebate up to ₹60,000).
  • Standard deduction: ₹75,000 for salaried people and pensioners — so a salary of up to ₹12.75 lakh pays no tax.
  • Marginal relief: just above ₹12 lakh, tax cannot exceed the income above ₹12 lakh. On a ₹13 lakh salary (₹12.25 lakh taxable), tax is ₹26,000 including cess, not ₹66,300.
  • Cess: 4% on tax plus surcharge. Surcharge applies above ₹50 lakh and is capped at 25% in this regime.

Old regime

Slabs (below 60): nil up to ₹2.5 lakh, 5% to ₹5 lakh, 20% to ₹10 lakh, 30% above. The basic exemption is ₹3 lakh at 60–79 and ₹5 lakh at 80+. The standard deduction is ₹50,000, and the rebate makes income up to ₹5 lakh tax-free. In exchange for higher rates, you can claim deductions such as 80C (₹1.5 lakh), 80D (health insurance), HRA, home-loan interest (₹2 lakh) and 80CCD(1B) NPS (₹50,000).

Which regime is better?

Tax on salary with no deductions other than the standard deduction:

SalaryNew regimeOld regime (no deductions)Old regime (₹3.75 lakh of deductions)
₹8 lakh₹0₹65,000₹0
₹12 lakh₹0₹1,63,800₹70,200
₹15 lakh₹97,500₹2,57,400₹1,40,400
₹20 lakh₹1,92,400₹4,13,400₹2,96,400
₹25 lakh₹3,19,800₹5,69,400₹4,52,400

For most people the new regime now wins. The old regime only comes out ahead with large deductions — roughly ₹4.5 lakh at a ₹10 lakh salary, ₹5.45 lakh at ₹15 lakh and ₹7.1 lakh at ₹20 lakh (on top of the standard deduction). That usually means a big HRA exemption and a home loan and full 80C.

The worked example — ₹15 lakh salary, ₹50,000 other income, ₹1.5 lakh 80C and ₹25,000 health insurance — pays ₹1,05,300 under the new regime and ₹2,18,400 under the old one.

Useful in both regimes

  • Employer's NPS contribution (within the salary-percentage limit) is deductible in both.
  • Standard deduction applies in both, at different amounts.
  • Interest on a let-out property and certain allowances also follow common rules.
